Referring now in detail to the drawing, IfII designates an atomizer embodying the invention. The same comprises a body I IV which may be made of vasingle piece of' metal.v Body II 'has-a bottom surface I'2, a top surface I3, parallel front and rear faces I4 and I5, and symmetrical-semicylindrical end faces I6 and IT.. The bottom and top faces 'I2 and I3I arefparallel to'one another. The body is formed with a drilled opening or bore I8,V extending 'from the bottom surface I2, upwardly and terminating in an upper surface I9, somewhat below the top surface I3.. The axis of the bore is at the axis of the semiecylindrical surface It, but the radius of the bore |123 is somewhat less than the radius of surface I6, thereby forming a semi-cylindrical wall 2.3, surrounding half of the bore, as shown in the drawing. Said wall is formed with a round drilled opening 2l below surface I3, the axis of the opening 2I pass- Y surface I'I, and forming a top Eat annular surfaced 24.1- Said body is also formed with a bore 25'A at the axis of said surface Il', and extending downwardly from the surface 24,;to. a point spaced above the bottom surface I2. The diameterv of. the bore 25 is less than thediameter of surfacev I.'I,y leaving a semi-cylindrical wall 23 partially surrounding said bore. The bores I3 andv 25 are parallel. to one another, and while the bore I8v isA open at thebottom, the 'bore' 25 is open, at its upper end. Between the bores I8 and 25, is a web'cr wall 21.. Said wall 2'Ifis formed with a drilled opening; 28', which inclines upwardly from bore I8 to bore 25. The opening or passage-23v is located ina plane: passing through the axes ofthe-bores I3 and 25,

and interconnects the bore I8 above its lower end,V

withr the bore 25, likewise, somewhatv above the lower end of the latter. The inclinationof bore 28' is such, that a drill may be passedlthroughthe lower end of bore I8 to effect a drilling operation for the opening 2&3.V Y

The: body I I is furthermorel formed witha horizontal drilledY opening, 3,51 interconnecting-f the upper end of bore I8 with the inwardly curved part-cylindrical surface. 2:3. Said' opening' 33 is offsetfrom aV planer passing through-the axes of the bores I8 and 25, and is tangent to the plane of surface 24 lying wholly above said plane. The opening 33 is a round opening and it is also substantially tangent to the bore I8, as shown in Fig. 2 of the drawing. It will be noted that at the ends of the part-cylindrical surface 25 are vertical edges 23a and 23h, butvthe sharpedges are preferably removed. Y

Fixed within the bore I8 Yis a liquid or perfume chamber 32,. Said chamber has a cylindrical wall 33 open at its lower end, and is formed at its upper p end with an end wall 34. The end wall 34 has a flat upper surface 35 located below the opening 2 I. The lower end edge 33 of the cylindrical wall 33 is located above the lower surface I2 of the body. The outer surface of the cylindrical wall 33 is grooved annularly, as at 3i, between its upper andlower ends' to reduce the amount of surface Contact between chamber 32 and the inner surface of bore I8. The outer surface of cylindrical wall 33, furthermore is formed with a longitudinal slot 38 communicating at its lower end. with' passage 28. The slot 33. terminates short of the upper end of chamber 32, as shown. in Fig.. 1- of the drawing.. The end wall 34 is formed with an upwardly and inwardly inclined through opening 33 communicating at its outer end with'theY upper end of slot 33. Said end wall 34. is also formedv in its upper surface with. a downwardly extending opening 40, communicating with the upper end. ofY opening 39. It willv be noted thatA the opening' 43 is offset from the axis of chamber 32..

Said end wall 34 is also formed with a verticall through-drilled opening 4I. The openings 4I) and. 4I are located in a plane' passing through the axes of bores I8 and 25, and on oppositesidesof theY axis of bore I8. The opening 4I communicates: with the interior of the chamber32.

End wall 34 is also formed with a drilled vertical through-opening 42, offset from the axis of bore IS, and located in a plane at right angles to the plane of the axes of bores I3 and 25.

The lower end of cylindrical wall 33 is-formed.

I with internal screw threads 44 for the purpose hereinafter appearing.

Means is provided for closing the lower endLof, the liquid chamber 32. Tol this end, there is screwed to the lower threaded end 44 of the liquid chamber, a screw cap 4.5. Cap 45 has an external threaded portion Itv engaging the internal' threadsl 44. Said cap also has an annular ange 4T having an external diameter, substantiallyequal to the internal diameter of bore I'81. The cap is under-cut, as at 43, to receive a washer or gasket 49 interposedv between the ange 41 andthe' lower end edge 33 of the chamber 32. It will now be understood thatf the chamber 32 is closed bythe cap 45. i

rI'he cap 45 may be formed with a slot 50, at' its lower end to receive a screw driver or` an edge of a coin, so. that; the cap may be unscrewedl or screwed into place.

The chamber 32 may be lled with perfume, or

other liquid to bey atomized and sprayed. S'ai'd: Y

. is the upper end of a liquid or perfume tube- 52'.

per end, the rotary member 55 is also formed with a cut-away portion 59, forming a flat vertical rectangular surface 66 extending down substantially to the axis of opening 2| and olfset from the axis of the rotary member. At the lower end of surface 69 is a flat horizontal surface 6|. Said horizontal surface 6I is formed with an opening` 62 which may extend down through to the lower end of `the rotary member. At the lower end of the rotary member is a shallow recess 63, and at the periphery of the recess is an upwardly extending annular groove 64 leaving an annular rim edge 65 which is turned inwardly to clamp a gasket 66 against the recess surface, the outer edge of the gasket being pressed into the groove 64. The gasket 66- contacts the upper surface 35 of the chamber 32. The gasket is made of Neoprene or the like material, and is formed with .openings 61, 68 and 69, adapted to register, in one angular position of the rotary member 55, with the openings 49, 4I and 42, respectively, of the liquid chamber 32. It will be noted that the gasket 66 is tightly clamped to the rotary member 55, and will rotate therewith, and when the rotary member is rotated to a position misaligning openings 61, 68 and 69 with respect to the openings 40, 4I and 42, respectively, said latter openings will be closed and sealed by said gasket. `The gasket may be selected of any suitable material which i will not deteriorate or be affected by alcohol, or by the perfume or liquid within the chamber 32.

The rotary member 55 is formed with a radial drilled spray opening 1I] co-axial with opening 2| and of somewhat smaller diameter than said opening 2|, and terminating short of the axis of said rotary member. It will be noted that the surface 6D is inclined rearwardly and inwardly with respect to the front and rear surfaces I4, I5. The rotary member 55 is furthermore formed with a vertical drilled opening 1I extending upwardly from the lower recessed surface 63, and commimicating with the bottom of the opening 18. The opening 1| registers with the opening 68 in the gasket 66, and hence will register in one position of the rotary member with the tube 52.`

The inner wall 12 of the opening 18 is flat, annular, and in a plane perpendicular to the surfaces I4 and I5 of the body in the position of the rotary member when the openings 61, 68 and 69 register with the respective openings in the upper end wall 34 of the chamber 32.

The rotary head 55 is furthermore formed with an upwardly inclined drilled opening 14 extending from the recessed surface 63 of the head to a point close to said surface 12. Passage14 is connected to surface 12 by an opening 15. The opening 15 is in the plane of the axes of the rotary member 55 and opening 16. The lower end of passage or opening 14 communicates with opening 61 in the gasket. Said rotary member 55 is furthermore formed with a vertical throughopening 11 extending from the lower recessl surface 63 to the top surface 51 of the rotary member and registers with the opening 69 in the gasket 66. Fixed within the opening 1I is a nozzle or jet tube 18 projecting upwardly into the opening 19. The lower end of the tube 18 is flush with the surface 63. The upper end of the nozzle or tube is formed with a restricted opening. The

upper end of said nozzle, furthermore, is substan tially at the axis of the opening 19, and hence close to the axis of the opening 15.

It will now be understood that when the rotary member is in the position shown in Fig. V1, with the openings 61, 6-8 and 69 registering with the openings 48, 4I and 42, respectively, air may pass from the bore 25 through passage 28, through slot 38, passage 39, opening 40, opening 61, passage 14, and opening 15. When air is forced through said openings and passages, the air will blow across the mouth of the nozzle 18. Liquid passing upwardly from the interior of chamber 32 through tube 52, opening 68, and tube 18 will be atomized by the stream of air coming out through the opening 15. The openings 42, 69 and 11 serve as an air vent to permit entry of air into the chamber 32 as the liquid is used up.

When the rotary head is rotated, the openings 40, 4I and 42 are sealed, and the opening 10 be-V comes misaligned with respect to the openings 2 and is, hence, likewise closed. The means for rotating the rotary head 55 will be explained here inafter.

Means is provided to press the rotary member 55 and its gasket 65, down against the upper surface 35 of the chamber 32. To this end, there is received in the opening 58, a pin 18, headed at itsV lower end as at 19. Interposed between the flange 19 and inner surface I9 is a coil compression spring 89. The spring is ofvarying diameter, its smaller end engaging the flange 19, and its large end engaging the surface I9. The spring 89 serves to depress the rotary member, and its gasket against the liquid chamber to insure a good seal.

Means is provided to pump air from the lower'` end of the bore 25 to passage 28 and. hence, through slot 38 for atomizing liquid passing upwardly through the nozzle 18. To this end, there is mounted for reciprocation, within the pump chamber 25, a pump or plunger 85. The same comprises, generally, of a piston 86 attached` toi upper end of said portion `89 is an externally` threaded, reduced axial stern 93 forming a shoulder 94 between portions 89 and 93. Below the shoulder 94, portion 89 is formed in one of. its faces with a horizontal blind opening 95, for the purpose hereinafter appearing.

The piston 86 is xed on the stem 90. It comprises a metal disc 95a formed with a centrals opening` through which the stem 9|] passes, and said disc contacts the under-shoulder 92. ,Contacting the underside of thedisc 95a is a cupshaped pump gasket 96 which may be made of` leather, synthetic plastics, or other suitablematerial. The gasket 96 has a flat top wall 91 and a skirted downwardly extending wall 98 frictionally` contacting the inner surface of the bore 25. ,Top wall 91 has a central opening through which the stem 89 passes. Disposed within the cup S8 and. xed onto the lower end of stem `9|), Vis a piston. clamp member |80. The member has atop.` flat annular wall 19| from which extends down` wardly, a tubular wall |02 surrounding` the stem, 38. Wall IIII contacts the undersideof UDP wall.

7 V9T of the gasket 96. At tlie'l'owerV end of tubular wall |021, is a conical shaped wall |03 having a flat undersurface. VThe'l'ower endoi tubular por,- tion isf riveted over against the fiat undersurface of portion |03', as at |04, thereby keeping members 952, 96 and' |08 in'` clam-pedassembled rel'ation with the `lower end of the piston rod 81. Y

The said portion |83 is'y formed at its outer periphery with a downwardly extending annular' flange |05. Interposed between the-underside of member |'03 and the bottom surface |38- of the bore 25, is a frusta-conical shaped coil compression spring |01 which normally urges the plunger or' pump 852 in an upward direction.

Screwed to the upper endv 93 of the piston rod 89 is `the knob or button 88. Said button has a top, nat, annular wall |69 and a downwardly extending central internally screwed portion H82, which is" screwed to the stem 93. The diameter offri/all` |209 is somewhat smaller than the diameter'of the surface 22. It will b'e noted than' when the* button 881s' depressed, the piston will force air' downwardly through the passage 28, and when pressure is released from the button 88, the'spring |81 will move the piston upwardly.

Means is provided to prevent rotation of the piston `85. ST0 this' end, there is xed in the upper end ofthe bore 25, a piston or pump guide If|=2. y VSaid pump guide comprises a substantially cylindrical portion I I3V forcev fitted into the upper endt of the pump' bore 25'. At the upper end of said portion H3, is an annular flange H4 contacting the upper surface 24. Extending up'- wardly from the'said portion H3 is a sleeve portion- H51 formed near its upper end with an external groove H6. The guide member H2' is formed. with a' through opening H1 of hexagonal shape to slidably rreceive the hexagonal piston rod 89. Said portion H3 and the sleeve H5 are formed with a through. slot H8 communicating with the hexagonal through. opening H1 and Aforms an extension thereof. The sleeve H thus has a slot all the' way through, and the slot H8 extends beyond the sleeve, as shown in Fig. 2 in the. drawing; The upper end edge H9 of sleeve H3. is disposed somewhat below the undersurface |20 of the top wall |09 of button 88', It will be understood that since the hexagonal rod or shaft 89 slidably fits within the through opening H1, thev piston 85 cannot rotate, but can only recip rocate. The lower end of portion H3 may be bevelled or chamfered. Furthermore, the outerV Q u |32. Said ring' is alsoy formedwith` a horizontal annular web or wall |34 spaced from the upper V and lower ends of wall |3|. The web |34-is formed withl a circular central opening E36 and with a downwardly extending part-cylindrical ilange |31 projecting downwardly from the web |34. The lower edges of flange |31 and wall |3| contact the upper surfaceV |22 of flange H4. The web |34 `is formed with a slot |38 extending from the circular through opening |36 and adapted in one angular' position of the ring, to register with the slot I I8. The sleeve l5 passes through the opening |36, and the ring may rotate about the sleeve is located just beneath the underside of the web surface of portion H3 may be knurled, if de- Fixed in the opening 95 of the piston rod 83 is a horizontal radial pin |2| projecting into slot H8. The pin |2| is locatedsomewhat above the upper surface 22 of theA flange H4. In said' uppersurfaceA |22 is a. downwardly extending through hole. |23 for' the' purpose hereinafter appearing.

Means is provided for releasably retaining the piston or pump 85 in fully depressed position, and for' misaligning' the rotary head 55 for sealing the openings in said head and closing' opening 2 I" |34. When the slot |38 in web |34 is in alignment with the slot H8 the piston 85 is released and may' be reciprocated up and down, since 'the |2| will pass through opening |38. HoweveigA should the ring |30 be rotated inl a clockwise di`d r'eotion, looking at Fig. 2 of the drawing, the slot |-38 will become misaligned with respect to the pin, and' said pin will then be engaged by the underside of the web |34 to keep the piston fromV rising. It will be noted that the groove H6 is locatedrjustl above the upper surface of the web |34. Received in said groove, is a split spring! ring 48 which contacts the upper surface of the'V web |'3'4 to prevent longitudinal movement o'f the ring, while permitting rotation of the latter'. Webl |34 is formed with a through opening |4| disposed in a plane at right angles to a plane" passing through the axis of the ring and bisecting slot |38. Interconnecting' the ring |30 andy the rotary head 55 isa link |43. Said com*- prises` a horizontal portion |44 passing" through the opening 38 and located'below web |34; and above the plane of surface 6|. Extendingdown'- wardly at one end of said portion 44A is' a leg |45 which rotatably engages within the opening |52- in the surface 6|' of the rotary head 55. At the" other end of said portion |44 is a through opening |46 registering with the opening' |'4`|'. Fixed within the opening 546 is an upwardly extendingl pin |41 rotatably engaging' within the opening' |4|. Y

Itv will now be understood that when the parts" are in a position shown in Figs. l, 2 andv 3, the" piston is released, and may be worked up and down by the thumb of the user and spring |01'. The rotary head has its openings alignedwith the openings in the oil chamber, and oil orV perfume or liquid therefrom willv be atomized, and` the spray will pass through the opening 2|. How-v ever, with the piston depressed to the position shown in. Fig. 1 should the ring" |30 be rotated;

in a clockwise direction, the web |34 willengage the pin |2| to' retain the piston in depressed con# dition, and at the same time, the rotary head 55I will be rotated in a` clockwise direction to mis-f align opening 10 with respect to opening 21|, so@ that part of the cylindrical surface of the' rotary member will close the opening 2|', and thev openings 14 and 42 and the nozzle 18', will besealed ofi and closed. Whenv the user desiresf thereafter 'toA use the atomizer, the ring |30 is again rotated, but in a counter-clockwise' direction, for' again aligning the slot |38 with pin |25', to` release the piston, andV thereby', also rotating. the head 55 to the irl-.use position of Figs. 1, 2' and'3. The spring' |01 will then lift thev piston',

and the user may then Work' the piston up"v down. for spraying or atom-izing perfume f-romf the-liquid chamber. The rotation of the ring' |l3| 9 in aclockwisedirection is limitedto a position where the link |43 contacts surface 60 of the rotary head, or one edge of flange |31 contacts pin |2|.

To limit rotation of the ring I3| in a counterclockwise direction, there is fixed within opening |23, a pin |50, which projects above surface |22. The pin is so located that one end of link |43 will contact said pin when the opening 'l0 is aligned with the opening 2l and the slot |38 is centered relative to the pin |2 I.

Means is provided to resiliently press the cylindrical gasket wall 98 against the inner surface of bore 25. To this end, there is mounted within the piston, and between walls IDI and |03 a ring shaped coil spring 86a, normally contacting and pressing outwardly against the cylindrical Wall 9B of the gasket to ensure good frictional contact between the gasketand the inner surface of the bore. It will thus be seen that there is provideda device in which the several objects of this invention are achieved and which'is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above setforth, it is to be understood that all matter herein set forth or shown in the accompanying drawings, is to be interpreted as illustrative and not in a limiting sense.

While the drawing shows the gasket 65 to be attached to the underside of the rotary valve head 55, if desired, the gasket may be attached to the upper end of the liquid chamber instead of to the rotary head. Insuch case, the underside of the rotary head would `be smooth, and the upper end of the liquid chamber would be formed with a shallow recess to receive the gasket and with an annular groove and annular rim flange cramped in to grip the edge of the press the same with the grooveV Having thus described our invention, we claim as new and desire to protect by Letters Patent of the United States: I
